This is really disappointing, but not unexpected. I’ve been using Nova for more than a decade and can’t get used to any other launcher I’ve tried so far. Everyone thought Nova would turn into an ad infested shell of itself once it was bought a few years ago. I guess this is worse since it will cease to function soon (maybe).

This is basically what I do, except the quicker way without using ADB to remove anything. Might try removing the junk though to see if it makes a difference. Launcher Manager and Flauncher makes an Onn 4K very snappy. Hard to beat for $20 and a little setup effort. I used to use Firesticks for years, but they get so slow and constantly revert my launcher changes. Finally got rid of them all.
